Application filed April 19, 1889. Serial No. 307,781. (No model.)

To all whom it may concern:

Be it known that I, JAMES J. SCHOLFIELD, a citizen of the United States,residing at Martinsville, in the county of Morgan and State of Indiana,have invented a new and useful Sight, of which the following is aspecification.

The invention relates to improvements in sights.

The object of the present invention is to enable the sight to beadjusted longitudinally along the barrel to adapt it to the eye of themarksman and the light.

- The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective View of a portion of agun-barrel provided with the improved sight. 'Fig. 2 is a reverse planview of the sight. Fig. 3 is a transverse section. V

Referring to the accompanying drawings, A designates a frame constructedof suitable material, preferably steel, and approximately rectangular inform. The frame A is letinto the barrel B or may be otherwise suitablysecured thereto, and it incloses within it a rod 0, upon which a sight Dis adjusted longitudinally along the said barrel. The rod is secured inthe rear end of the frame and extends along the same in the spacebetween its sides to a point within a short distance'of the front end,whereby, when it is desired, the sight D may be removed from the rod orplaced thereon by lifting the free end'c' from the frame A, therebyallowing the sight to be readily slipped ofi.

The sight is of any desirable construction and is secured to a slide orbase D, which is of the same width as the space between the sides andfits snugly between the latter, and is provided with a slot cl, throughwhich passes the rod C. The sight is adjusted along the rod to thedesired point, and is retained in that position against accidentalslipping by a set-screw E, which extends through the upper portion ofthe sight and engages the rod G,'Wl1l(3l1 is preferably threaded orroughened to enable the set-screw E to obtain a better hold.

The adjustable sight may be used singly or in combination with any otherstyle of sight, and it will readily be seen that sights constructed inaccordance with this invention can be adjusted to any desired positionto suit the eye of the marksman and the light.

WVhat 1 claim is p 1. The combination, in a gun-sight, of therectangular frame designed to be rigidly at tached to the barrel of agun, the rod secured to the rear of the frame and extending to a pointwithin a short distance of the front thereof, and a sight sliding uponsaidrod, substantially as described.

2. The combination, in a front sight, of the stationary rectangularframe, the rod secured in the same and extending withina short distanceof the front end, the slide adapted to move along said rod between thesides of the frame,-and a sight mounted upon the slide and provided witha set-screw, substantially as described.

3. A front sight comprising the stationary frame designed to be securedrigidly to the front of a gun-barrel, the rod secured between the sidesof the frame and inclosed thereby,

the slide mounted on said rod and fitting snugly between the sides ofthe frame, the sight secured upon the slide, and suitable means forsecuring the slide to the rod, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
